I just got a new mag 250 and its spewing out air bubbles like its going out of style. Am I just jumping the gun and need to give a a few days or is this a problem? Its been a full 24 hrs already and the bubble are not going anywhere. I also see that when I open the top its not completely full so I refill it and the bubbles go away. Then a minute later the bubbles are back and when I open it again its half full again. Any suggestions to fix this?
